1.0.0[−][src]Struct nom::lib::std::ops::RangeFrom
A range only bounded inclusively below (start..
).
The RangeFrom
start..
contains all values with x >= start
.
Note: Currently, no overflow checking is done for the Iterator
implementation; if you use an integer range and the integer overflows, it
might panic in debug mode or create an endless loop in release mode. This
overflow behavior might change in the future.
Examples
assert_eq!((2..), std::ops::RangeFrom { start: 2 }); assert_eq!(2 + 3 + 4, (2..).take(3).sum()); let arr = [0, 1, 2, 3, 4]; assert_eq!(arr[ .. ], [0,1,2,3,4]); assert_eq!(arr[ .. 3], [0,1,2 ]); assert_eq!(arr[ ..=3], [0,1,2,3 ]); assert_eq!(arr[1.. ], [ 1,2,3,4]); // RangeFrom assert_eq!(arr[1.. 3], [ 1,2 ]); assert_eq!(arr[1..=3], [ 1,2,3 ]);
Fields
start: Idx
The lower bound of the range (inclusive).
Methods

Idx: PartialOrd<Idx>,
pub fn contains<U>(&self, item: &U) -> bool where
Idx: PartialOrd<U>,
U: PartialOrd<Idx> + ?Sized,
1.35.0[src]
Idx: PartialOrd<U>,
U: PartialOrd<Idx> + ?Sized,
Returns true
if item
is contained in the range.
Examples
use std::f32; assert!(!(3..).contains(&2)); assert!( (3..).contains(&3)); assert!( (3..).contains(&1_000_000_000)); assert!( (0.0..).contains(&0.5)); assert!(!(0.0..).contains(&f32::NAN)); assert!(!(f32::NAN..).contains(&0.5));

impl SliceIndex<str> for RangeFrom<usize>
1.20.0[src]
Implements substring slicing with syntax &self[begin ..]
or &mut self[begin ..]
.
Returns a slice of the given string from the byte range [begin
,
len
). Equivalent to &self[begin .. len]
or &mut self[begin .. len]
.
This operation is O(1)
.
Prior to 1.20.0, these indexing operations were still supported by
direct implementation of Index
and IndexMut
.
Panics
Panics if begin
does not point to the starting byte offset of
a character (as defined by is_char_boundary
), or if begin >= len
.
type Output = str
